Concealed guns protect not only those who carry them but also those who do not. If concealed guns become widespread, then a mugger or a car jacker has no way of knowing who has one and who does not. It makes being a mugger or a car jacker a less safe occupation. Gun control laws are in effect occupational safety laws -- OSHA for burglars, muggers, car jackers and others.
The fatal fallacy of gun control laws in general is the assumption that such laws actually control guns. Criminals who disobey other laws are not likely to be stopped by gun control laws. What such laws actually do is increase the number of disarmed and defenseless victims.
